Operation Sentinel Justice is a large-scale U.S. Army Reserve training exercise that enhances Soldier and unit readiness, validates capabilities, and improves missions’ effectiveness through realistic, multi-echelon training in a dynamic operational environment. The medical training component is a part of Global Medic, the Army Reserve’s premiere medical readiness training exercise that is planned and executed by the Medical Readiness and Training Command.

U.S. Army Reserve medical personnel assigned to the 385th Field Hospital, 807th Theater Medical Command, evaluate simulated casualties during Operation Sentinel Justice at Camp Beauregard, La., June 11, 2026. The training scenario allows Army Reserve medical personnel to practice patient assessment, triage and treatment procedures in a realistic operational environment. Operation Sentinel Justice strengthens medical readiness by validating Soldiers' ability to provide expeditionary health care in support of large-scale combat operations and joint force missions.

Soldiers from the 628th Forward Resuscitative Surgical Detachment pushed their capabilities closer to the front lines during a joint training exercise at the Joint Readiness Training Center (JRTC), testing how advanced surgical care can be delivered earlier in the evacuation chain to improve survival outcomes.

During May 2026, the San Antonio-based unit trained alongside Role 1 medical elements from the 10th Mountain Division, an integration that challenged the FRSD to operate further forward than its standard Role 2 position.

"Our main training objective this time around is to see how we incorporate with the Role 1 and with the 10th Mountain Division. Are the skills we provide to the frontline conducive to their mission as well." said Maj. Joshua Strommen, an emergency medicine physician with the 628th FRSD. "Our objective is to see how well we can put our skills in with their skills."

Strommen said the exercise also forced the unit to confront a central question of large-scale combat operations: whether moving surgical capability forward could meaningfully reduce casualties before patients reach higher echelons of care.

"Our mission doesn't change," he said. "But the help that we can lend in those scenarios can really bring cutting-edge, life-saving interventions closer to the point of injury."

Spc. Angel Martinez, a practical nursing specialist and noncommissioned officer in charge of the ICU section for the 628th FRSD, said his role centered on managing post-operative patients following damage control surgery, keeping them stable until they could be transported to a higher echelon of care or returned to the fight.

He said training under large-scale combat operations conditions added a layer of complexity the unit doesn't face at Role 2, where evacuation timelines are shorter and the surgical element operates further from direct contact.

"Being on the front lines with the Role 1 medical unit, normally we're further back, but being in the front lines with them and seeing the capabilities that they have augmented with what we're capable of doing has been a real challenge, and a good challenge, to provide better care for soldiers," Martinez said.

The unit, which typically deploys as a 20-person team capable of splitting into two 10-person elements, also faced environmental challenges during the rotation. Accustomed to San Antonio's hot, dry climate, soldiers contended with persistent rain and humidity throughout the exercise.

"It's been hot and wet," Martinez said. "It's been raining the whole time we've been here, just embracing the suck."

Strommen said the ultimate measure of success for the rotation was simpler than any tactical metric.

"The biggest focus is for us to know what our roles individually are so that we can resuscitate a patient and give them a chance to get back home," he said.

For 251 years, America’s Army has answered the nation’s call. Today, we celebrate the legacy of service, sacrifice, and readiness that connects generations of Soldiers—past and present. Happy Birthday, U.S. Army!

Maj. Gen. Michael L. Yost visited Joint Emergency Medical Exercise 2026 at Fort Hood, Texas, on June 3, 2026, where he observed training and received updates on the exercise's role in preparing military medical professionals for future operations. Also attending was Maj. Gen. Andy Cox of the British Army, highlighting the multinational partnerships that contribute to military medical readiness.

JEMX 2026 is a large-scale, multi-service combat casualty care exercise designed to train and validate 144 medical professionals representing 25 Army Areas of Concentration and Military Occupational Specialties from the U.S. military, NATO allies and partner nations. The exercise bridges the gap between clinical practice and battlefield medicine by placing participants in realistic, contested operational environments that test critical medical skills, interoperability and patient care across the continuum of treatment.

The 2nd Medical Brigade welcomed new leadership during a Change of Command ceremony June 7 at Camp Parks, California. Maj. Gen. Michael Yost, commanding general of the 807th Theater Medical Command, officiated as Col. David Hatch relinquished command to Col. Jacqueline Ojimba.

Congratulations to CW4 Jorge Diaz, the 807th Theater Medical Command's Information Services Technician, on being featured in a recent Warrant Officer Wednesday profile. With 35 years of service, CW4 Diaz exemplifies technical excellence, leadership and dedication to the Army Reserve mission.
